MaxCyte Presents Updates on First-in-class CARMA™ Platform at Upcoming Meetings

Clinical-stage CARMA platform delivers non-viral mRNA-based cell therapies

Faster manufacturing speeds, broader therapeutic applications, combination opportunities and repeat dosing potential

Gaithersburg, Maryland - 30 September 2019 - MaxCyte (LSE: MXCT, MXCS), the global cell-based therapies and life sciences company, announces its planned participation at five upcoming meetings. These conferences and events will demonstrate how MaxCyte is driving the development of the next generation of cell-based medicines with its proprietary CARMA™ platform.

CARMA is MaxCyte's clinical-stage, non-viral, mRNA-based cell therapy platform that allows for the transfection of mRNA into cells and provides a simple, rapid-to-manufacture, dose-controllable product. CARMA requires less than one day to manufacture therapies for patients, where existing CAR-T therapies require one to two weeks or more to manufacture. MaxCyte's wholly-owned lead CARMA candidate, MCY-M11, is currently being evaluated in a Phase I clinical trial in patients with advanced ovarian cancer and peritoneal mesothelioma.

Details of the conferences are as follows:
